Problems with chinese MP4
 

Hi folks

This is my first post here

I recently received this MP4 player

$28.70 - Designer's 2.8" Touch Screen Portable Multi-Media Player w/ 1.3MP Camera/FM Radio/AV OUT/TF (4GB) - MP3/MP4 Players

But it have problems and I dont know how to repair it. I discussed the problems here

DealExtreme Product Forum: Defective product? Please help!

Basically it has 2 problems, the volume increases by itself and it can not be see by the PC so I can not transfer files to it.

It uses ATJ2237T chip and I dont know if there is a firmware update available, and How to.

Any help? Thanks!
